Lab assignment

Creating a folder or sub-folder for chapter 01 files

Within the Chapter 1 Connexions modules you were given directions on how to install the Bloodshed Dev-C++ 5 compiler/IDE and to test your installation with the Compiler_Test.cpp source code file. If you have not done this, return to the Connexions materials and complete this task.

In the compiler installation directions you were asked to make a folder named: Cpp_Source_Code_Files. All of your lab assignments in this course assume you have that folder on the same drive as your compiler (either drive C: your hard disk drive, or on a flash drive). If you don’t have that folder, go create it now.

Depending on your compiler/IDE, you should decide where to download and store source code files for processing. Prudence dictates that you create these folders as needed prior to downloading source code files. A suggested sub-folder for the Bloodshed Dev-C++ 5 compiler/IDE might be named:

  • Chapter_01 within the folder named: Cpp_Source_Code_Files

If you have not done so, please create the folder(s) and/or sub-folder(s) as appropriate.

Download the lab file(s)

Download and store the following file(s) to your storage device in the appropriate folder(s). You may need to right click on the link and select "Save Target As" in order to download the file.

Download from Connexions: Compiler_Test.cpp

Detailed lab instructions

Read and follow the directions below carefully, and perform the steps in the order listed.

  • Navigate to your sub-folder: Chapter_01 and rename the Compiler_Test.cpp source code file to: Lab_01.cpp
  • If you are having problems seeing the file extensions, visit the “Show Hide File Extensions” instructions within the Appendix.
  • Start your compiler and open the source code file. Carefully make the following modifications:
  • Change the comments at the top, specifically:
  • The filename should be: Lab_01.cpp
  • Purpose should be: Average the weight of three people
  • Remove the next 2 lines of comment talking about the main idea
  • Author: put your name and erase my name and copyright
  • Date: Put today's date
  • Remove the next 3 lines of comment dealing with licensing (don't erase the asterisk line)
During the rest of the course you will often use a source code file provided by the instructor as your starting point for a new lab assignment. Sometimes you will use a source code file that you have created as your starting point for a new lab assignment. Either way, you should modify the comments area as appropriate to include at a minimum the four lines of information (filename, purpose, author and date) as established in this lab assignment.
  • We are now going to make simple modifications to this program so that it is able to average the weight of three people. Do the following:
  • Within the variables area, change the variable names for age1 and age2 to weight1 and weight2. Add another variable of integer data type with the identifier name of weight3.
  • The input area has two prompts and requests for data from the user. They are paired up – a prompt and getting data from the keyboard. We need to modify the prompt to ask for weight instead of age. We need to change the variable name from age1 to weight1. Do this for the second pair that prompts and gets the second data item. Create a third pair that prompts and gets the third data item.
  • The process area has only one line of code and we need to make changes that add the weight3 and divides by 3.0 instead of 2.0. The code should look like this:
  • answer = (weight1 + weight2 + weight3) / 3.0;
  • The output area needs the text modified from ages to weights.
  • Build (compile and run) your program. You have successfully written this program if when it run and you put in the three weights; it tells you the correct average.
  • After you have successfully written this program, if you are taking this course for college credit, follow the instructions from your professor/instructor for submitting it for grading.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
